/**
* Represents Java source files somewhere on the classpath. This might be
* somewhat of a unique situation, since often source isn't on the classpath,
* only class files are. However, there may be times when you want to ship
* both the classes and source for a library and put them on your classpath
* for simplicity of integrating with this code completion library. In such a
* case, you would use a ClasspathLibraryInfo and use this class
* for the source location.
*
* This class has no state; any classes it's asked about, it assumes it can
* find the corresponding .java file somewhere on the classpath using the
* class's ClassLoader.
